Built from solid carbide, it delivers the rigidity and wear resistance needed when working through cast iron, stainless steel, steel, and non-ferrous metals. The bit measures 0.2188 inches (7\/32 inch) in diameter with an overall length of 2.375 inches, making it suited for short-hole drilling in tight clearances. A 135-degree split point starts on contact without a center punch and reduces walking on hard surfaces. The slow spiral flute geometry is optimized for chip evacuation in the materials this bit is designed to cut.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in screw machine operations, CNC drilling, and production machining where hole accuracy and tool life are critical. The straight-cylindrical shank seats directly in standard drill chucks and collets without modification. Typical applications include drilling ferrous and non-ferrous components in manufacturing, metal fabrication, and maintenance repair operations. The 3xD flute-to-diameter ratio and parallel web configuration support consistent performance across short-depth drilling cycles. It is sold individually and is appropriate for use in both manual and automated machine setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and eliminates center-punch requirements on most metals\u003c\/li\u003e\n  \u003cli\u003eSlow spiral flute geometry promotes chip clearance when drilling cast iron, stainless steel, and steel\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web design lowers cutting resistance and improves hole entry performance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.2188 inches diameter fits standard drill chucks and collets directly\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches supports close-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw machine, CNC, and production drilling applications targeting cast iron, non-ferrous metal, stainless steel, and steel workpieces.

Seat the straight-cylindrical shank fully in the chuck or collet and verify runout before beginning a drilling cycle. Confirm that cutting speeds and feeds are set to values appropriate for solid carbide tooling in the specific workpiece material being drilled, as solid carbide requires different parameters than high-speed steel. Do not use this bit on materials outside its rated workpiece range, as improper application will cause premature breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/32 inch (0.2188 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Slow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 205\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M.A. FORD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20521870T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51741879435570,"sku":"20521870T","price":76.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f08e4cc86bc9f13b401ef4fe0fdfc632_9b76611b-0f9b-4efc-ae55-1e31ad20ab83.jpg?v=1788834005","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20521870t-screw-machine-drill-bit-7-32-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
